XDPE19283D-0000 Digital dual loop 8-phase controller for AMD™ SVI3 server, workstation, and high-end desktop applications
Overview
Core voltage is provided by a multi-phase buck regulator controlled by XDPE19283D that can be configured in one of the following phase combinations between the two loops: 8+0 to 4+4. Command and monitor functions are controlled through the SVI3 interface, supporting dynamic voltage changes (VOTF), power states (PS), and VR telemetry and status requirements. XDPE19283D provides the ultimate system solution in terms of flexibility and stability.
XDPE19283D-0000 is available on demand only. For complete data sheets and additional information please contact us here.
